COMBINED CHURN AND BUTTER-WORKER.

Specification of Letters Patent.

Patented Feb. 27, 1912.

Application filed October 13, 1910. Serial No. 586,908.

To all whom it may concern:

Be it known that I, LEVI A. DIsnRow, a citizen of the United States, residing at Owatonna, in the county of Steele and State of Minnesota, have invented certain new and useful Improvements in Combined Churns and Butter-Workers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide an improved combined churn and butter worker and, to this end, it consists of the novel devices and combinations of devices hereinafter described and defined in the claim.

In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings, Figure l is a view chiefly in side elevation, but with some parts in vertical section, showing my improved machine; Fig. 2 is a transverse section taken through the churn on the line m m of Fig. 1; and Fig. 3 is a front end elevation of the machine, with some parts sectioned on the line m m ofFig. 1.

The body of the churn and butter worker is in the form of a horizontally disposed drum 1 having fixed heads. One head, towit, the rear head of the drum, is provided with a trunnion 2 journaled in a bearing pedestal 3; and the other head of the drum is rigidly secured to a large spur gear 4 having a hollow trunnion 5 that is journaled in a bearing pedestal 6. The pedestals 3 and 6 are shown as tied together in the usual way by tie bars 7 shown as tubular in form. The drum 1 is provided with the customary normally closed peripheral.

' doors 8.

The gear 4 is provided with radial spokes that are offset laterally from the adjacent drum head, to afford clearance for a pair of intermeshing gears 9 and 10, which gears are supported as presently described.

Located within the drum, at the axis thereof, is a working roller 11 provided with a shaft 12 journaled in the drum heads and, at one end, extended outward and journaled also in the hollow trunnion 5. The noted gear 9 is secured to the said roller shaft 12, and a similar spur gear 13 is secured to the extreme outer end of the said shaft. Also working within the drum is a second working roller 14. This roller 14 is located adjacent to the roller 11, extends parallel therewith, and its shaft 15 is fournaled in the drum heads and, atone end, is extended outward so that the gear 10, already noted, is secured thereto. A wide lifting shelf 16 extends from head to head of the drum, radially inward from the shell of the drum, and serves to pick up the but ter on the rising side of the drum and to deliver the same to the two positively driven working rollers 11 and 14. Also located within the drum are several narrow cleats 17 which prevent too much slipping of the butter within the drum. The cleats 17 and lifting shelf 16 are spaced approximately equi-distant, that is, they are located approximately 120 degrees apart. This, in the most efficient manner, positions the cleats so that they will assist in the collection of the butter for proper delivery to the lifting shelf.

Journaled in a suitable bearing on the pedestal 6 is a countershaft 18 which car ries a driving pulley 19, a spur gear 20 and a spur pinion 21. A power-driven belt, not shown, will run over the pulley 19. The pinion 21 meshes with the large gear 4 on the head of the drum. The gear 20 meshes with an intermediate gear 22 suitably journaled on the pedestal 6 and meshing with the gear 13 of the roller shaft 12.

With the connections described, when the pulley 19 is rotated in the direction of the arrow marked thereon in Fig. 1, the drum 1 will be rotated in the direction of the arrow marked thereon in Fig. 2, and the rollers 11 and 14 will be rotated in the directions of the arrows marked adjacent thereto, in said Fig. 2. Thus it will be seen that the axial roller 11 is driven in a direction reverse to the direction of the drum, and that the two rollers 11 and 14 are driven in reverse directions so that they will both cooperate to positively work downward between them the butter which is delivered thereto by the lifting shelf 16. Also, it is evident that the rollers '11 and 14 will be driven at a relatively high speed as compared with the speed of the drum 1.

In practice, I have found that it is im-' portant that both of the working rollers be positively driven and that the best results can be obtained by locating one of the said positively driven working rollers at the axis of the drum and with the other working roller and the lifting shelf eccentric to the axis of the drum and on the same side of the axis of the drum, so that the eccentric s roller and lifting shelf revolve around the 10 driving connections required to positively rotate the two cooperating rollers.

What I claim is:

The combination with an approximately cylindrical drum mounted to rotate on an 15 approximately horizontal longitudinal axis and having rigid heads, of a pair of cooperatmg horlzontal working rollers located within said drum, one thereof being located with its axis co-incident with the 20 axis of said drum and having a shaft extended axially outward from said drum, and the other roller being carried by the Copies of this patent may be obtained for five cents each, by addressing the drum heads and having a shaft extended at one end through one head of said drum, the space in the drum diametrically opposite to the eccentrically located roller being entirely clear or free of obstructions, a lifting flight extending inward from the shell of the drum on the same side of the drum as the eccentric roller in a plane that is approximately tangential to the working face of said eccentric roller and which plane extends approximately between the axes of said two rollers, and means including interineshing gears on the projecting portions of the said roller shafts, for positively rotating the said two rollers in opposite directions, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.
